How to: find game object with tag in hierarchy and toggle mesh renderer

Hi guys,

I hope someone could help me a bit..
I am trying to find runtime instatiated prefabs (clones) of a Game Object with a specific tag and than using the Toggle to turn off (and back on) the mesh renderer for these objects..

I thought to make a empty game object and than add a script to that and than mapping the Script on the UI Toggle (On Value Changed Boolean and setting the GameObject to SetActive... but I have been only able to deactivate the object with this:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Testing: MonoBehaviour
5. {
6.     GameObject[] MyTagObject;
7.  
8.     void Start()
9.     {
10.         Ceiling = GameObject.FindGameObjectsWithTag("MyTag");
11.  
12.         foreach (GameObject r in MyTagObject)
13.         {
14.             r.GetComponent<MeshRenderer>().enabled = false;
15.             r.GetComponent<Collider>().enabled = false;
16.         }

I would very much appreciate if anyone would know how to toggle the mesh renderer back on with the toggle..

any ideas?
